8、tatement on the Use of American Welding Society StandardsAll standards (codes, specifications, recommended practices, methods, classifications, and guides) of the AmericanWelding Society (AWS) are voluntary consensus standards that have been developed in accordance with the rules of theAmerican Nati

9、onal Standards Institute (ANSI). When AWS American National Standards are either incorporated in, ormade part of, documents that are included in federal or state laws and regulations, or the regulations of other govern-mental bodies, their provisions carry the full legal authority of the statute. In

10、 such cases, any changes in those AWSstandards must be approved by the governmental body having statutory jurisdiction before they can become a part ofthose laws and regulations. In all cases, these standards carry the full legal authority of the contract or other documentthat invokes the AWS standa

11、rds. Where this contractual relationship exists, changes in or deviations from requirementsof an AWS standard must be by agreement between the contracting parties.AWS American National Standards are developed through a consensus standards development process that bringstogether volunteers representi

12、ng varied viewpoints and interests to achieve consensus. While the AWS administers theprocess and establishes rules to promote fairness in the development of consensus, it does not independently test, evalu-ate, or verify the accuracy of any information or the soundness of any judgments contained in

13、 its standards.AWS disclaims liability for any injury to persons or to property, or other damages of any nature whatsoever, whetherspecial, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, or relianceon this standard. AWS also makes no guarante

14、e or warranty as to the accuracy or completeness of any informationpublished herein.In issuing and making this standard available, AWS is neither undertaking to render professional or other services for oron behalf of any person or entity, nor is AWS undertaking to perform any duty owed by any perso

15、n or entity to someoneelse. Anyone using these documents should rely on his or her own independent judgment or, as appropriate, seek theadvice of a competent professional in determining the exercise of reasonable care in any given circumstances. It isassumed that the use of this standard and its pro

16、visions are entrusted to appropriately qualified and competent personnel.This standard may be superseded by the issuance of new editions. Users should ensure that they have the latest edition.Publication of this standard does not authorize infringement of any patent or trade name. Users of this stan

17、dard acceptany and all liabilities for infringement of any patent or trade name items. AWS disclaims liability for the infringement ofany patent or product trade name resulting from the use of this standard.Finally, the AWS does not monitor, police, or enforce compliance with this standard, nor does

18、 it have the power to do so.On occasion, text, tables, or figures are printed incorrectly, constituting errata. Such errata, when discovered, are postedon the AWS web page (www.aws.org).Official interpretations of any of the technical requirements of this standard may only be obtained by sending a r

19、equest, inwriting, to the appropriate technical committee. Such requests should be addressed to the American Welding Society,Attention: Managing Director, Technical Services Division, 550 N.W. LeJeune Road, Miami, FL 33126. With regard totechnical inquiries made concerning AWS standards, oral opinio

20、ns on AWS standards may be rendered. These opinionsare offered solely as a convenience to users of this standard, and they do not constitute professional advice. Such opinionsrepresent only the personal opinions of the particular individuals giving them. These individuals do not speak on behalfof AW

21、S, nor do these oral opinions constitute official or unofficial opinions or interpretations of AWS. In addition, oralopinions are informal and should not be used as a substitute for an official interpretation.This standard is subject to revision at any time by the AWS C5 Committee on Arc Welding and

22、 Cutting. It must bereviewed every five years, and if not revised, it must be either reaffirmed or withdrawn. Comments (recommendations,additions, or deletions) and any pertinent data that may be of use in improving this standard are required and should beaddressed to AWS Headquarters. Such comments

23、 will receive careful consideration by the AWS C5 Committee on ArcWelding and Cutting and the author of the comments will be informed of the Committees response to the comments.Guests are invited to attend all meetings of the AWS C5 Committee on Arc Welding and Cutting to express theircomments verba

24、lly. Procedures for appeal of an adverse decision concerning all such comments are provided in theRules of Operation of the Technical Activities Committee. A copy of these Rules can be obtained from the AmericanWelding Society, 550 N.W. LeJeune Road, Miami, FL 33126.This page is intentionally blank.
